Detailed ways

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

Fig. 1 is a flow chart of a screen brightness adjustment method shown in an embodiment of the present disclosure, which is applied to a terminal including a display screen, and the terminal includes a plurality of optical sensors. As shown in Fig. 1 , the screen brightness adjustment method includes the following steps:

S11. Determine the actual luminous brightness of the light source according to the brightness values of the light sources detected by the optical sensors;

S12. Adjust the display brightness of the display screen according to the actual luminous brightness.

In an embodiment of the present disclosure, the terminal device includes: a mobile device and a fixed device; the mobile device includes: a mobile phone, a tablet computer, or a smart speaker with a display screen, and the like. The fixed device includes but not limited to a personal computer (Personal Computer, PC).

The terminal device includes a display screen capable of displaying image frames. The terminal is also equipped with a light sensor, which can be set under the display screen, and can convert the ambient light passing through the display screen into an electrical signal, so that the terminal can determine the brightness of the ambient light according to the electrical signal. For a terminal with a full screen, the light sensor disposed under the display screen realizes the detection of ambient light by detecting the light transmitted through the space gap between the display units.

As mentioned above, the optical sensor is limited by the receptive field (field of view), and the sensed light intensity value will be smaller than the real value. For a terminal with a full screen, the severity of this problem is aggravated. The reason is that the field of view of the optical sensor placed under the screen is even smaller, and in practical applications, it only has a receptive field of 45 degrees, so it may not be able to feel the actual light intensity on the top and back of the mobile phone, causing the optical sensor to detect The light intensity is not accurate enough.

Figure 2 is an example diagram of the field of view of an optical sensor under the screen in an embodiment of the present disclosure. Spend.

Typically, the optical sensor senses the exact light intensity if the terminal is directly below the light source. On the contrary, if there is an included angle from the light source, and the included angle is too large or even exceeds the field of view of the optical sensor, the perception ability of the optical sensor will be reduced by more than 50%, and the measurement will be too small. It should be noted that, in the disclosed embodiments, the position of the light source relative to the terminal refers to the position of the light source relative to the field of view angle of the optical sensor in the terminal.

FIG. 3 is an example diagram 1 of the positions of the light source and the optical sensor in an embodiment of the present disclosure. As shown in FIG. 3 , the light source is at the center of the field of view of the optical sensor, and the data measured by the optical sensor is close to the real value. FIG. 4 is an example diagram 2 of the positions of the light source and the optical sensor in the embodiment of the present disclosure. As shown in FIG. 4 , the light source is outside the field of view range of the optical sensor, and the data measured by the optical sensor is smaller than the real value.

5 is an example diagram of light intensity sensed by an optical sensor in an embodiment of the present disclosure. As shown in FIG. 5 , the abscissa indicates the position of the terminal relative to the light source, and the ordinate indicates the light intensity value sensed by the optical sensor. Figure 5 includes the curves of light intensity sensed by two optical sensors. From the trend of the two curves, it can be seen that within the range of plus or minus 30 degrees, the light intensity value sensed by the optical sensor is relatively large, and the angle deviation exceeds this range , and the larger the deviation, the smaller the light intensity value sensed by the optical sensor. It should be noted that the inconsistency of the curves of the light intensities sensed by the two optical sensors in the terminal may be caused by the difference in positions of the two optical sensors.

From the above, it can be seen that the light intensity detected by the optical sensor may not accurately reflect the actual situation, and thus the brightness of the display screen may be adjusted based on the ambient light detected by the optical sensor, and there may be adjustment deviations. For example, the adjustment of screen brightness is too dark, which affects the user's reading experience.

In this regard, the present disclosure proposes a screen brightness adjustment method. In step S11, the actual luminance of the light source is determined according to the luminance values of the light source detected by multiple optical sensors, and then in step S12, based on the actual luminance of the light source. Adjust the display brightness of the display.

In an embodiment, the light source includes: a point light source or a line light source.

In the embodiments of the present disclosure, a point light source or a line light source refers to light emitted by an electronic device capable of emitting light, excluding light emitted by sunlight. The reason is that the radiation range of sunlight is wide, and the light intensity is relatively consistent in any direction, so there will be no problem of detection deviation caused by the limitation of the field of view of the optical sensor. On the other hand, the radiation range (irradiation area) of a point light source or a line light source is limited because there is a problem of causing detection deviation of the optical sensor.

In the embodiments of the present disclosure, when determining the actual luminance of the light source according to the brightness values of the light source detected by multiple optical sensors, for example, considering that the light intensity value sensed by the optical sensor is relatively small due to the limitation of the viewing angle, the In one embodiment, the maximum value among the luminance values of the light sources detected by multiple sensors may be used as the actual luminous luminance, so as to reduce the deviation. In another embodiment, the average value of the luminance values of the light sources detected by a plurality of optical sensors may be multiplied by a predetermined coefficient as the actual luminous luminance. The predetermined coefficient may be a value suitable for most situations set according to the curve shown in FIG. 3 , for example, the predetermined coefficient value is 1.3.

In the embodiments of the present disclosure, after obtaining the actual luminous brightness of the light source, the terminal can adjust the display brightness of the display screen according to the actual luminous brightness. For example, when the ambient light brightness information is high, the display brightness of the display screen can be increased; when the ambient light brightness information is low, the display brightness of the display screen can be reduced to suit the user's eyes.

It can be understood that the disclosure utilizes the brightness values of the light sources detected by multiple optical sensors in the terminal to determine the actual luminous brightness of the light source and then adjust the display brightness of the display screen, which can improve the accuracy of the adjustment and improve the user experience .

In one embodiment, the determining the actual luminous brightness of the light source according to the brightness value of the light source detected by each of the optical sensors includes:

According to the brightness value detected by each of the optical sensors, the predetermined positional relationship between the optical sensors, and the preset functional relationship, determine the actual luminous brightness of the light source; wherein, the preset functional relationship represents the light source and the terminal The mapping relationship between the included angle between the light source and the actual luminous intensity of the light source, and the brightness value collected by the optical sensor.

In the embodiments of the present disclosure, when determining the actual luminous brightness of the light source according to the brightness values of the light sources detected by the optical sensors, the predetermined positional relationship and the preset functional relationship between the optical sensors can also be combined.

Wherein, the predetermined positional relationship between the optical sensors represents the relationship between the orientations of the viewing angles of the optical sensors. Taking two optical sensors as an example, if the positions between the two optical sensors are vertical, the field of view of one optical sensor can face the display screen, while the field of view of the other optical sensor can face the frame of the terminal, such as the top of the mobile phone; If the positions between the two optical sensors are parallel, the viewing angles of the two optical sensors can both face the display screen. Of course, the present disclosure may also have three or more optical sensors, and the positions between the optical sensors are predetermined in advance.

In this embodiment, the preset functional relationship can be characterized by the following formula (1):

L*=f(L,θ) (1)

Among them, L represents the actual luminance of the light source, θ represents the angle between the light source and the terminal, and L* represents the brightness value collected by the optical sensor.

It should be noted that the preset functional relationship of the present disclosure can be obtained by fitting the following experimental data: when the light source is at the position of ±90° of the optical sensor, the light sensitivity of the optical sensor is 0; while the light source is directly above the optical sensor (0°) When the light sensitivity is 100%, the actual luminous brightness of the light source can be detected correctly; when the light source is at the 45° position of the optical sensor, the light sensitivity is halved. The curve corresponding to the functional relationship obtained based on the above data is the standard FOV curve.

In this embodiment, since the luminance values detected by each optical sensor are known and the predetermined positional relationship between each optical sensor is known, then the actual luminous brightness of the light source can be obtained by establishing a set of equations based on the above formula (1).

It can be understood that, the present disclosure constructs a system of equations based on the above method to obtain the actual luminous brightness of the light source, which has a small amount of calculation and is simple and convenient.

In one embodiment, the terminal includes a first optical sensor and a second optical sensor, the first optical sensor is located below the display screen, and the field angle of the first optical sensor faces the display screen; The second optical sensor is close to the frame of the terminal, and the field angle of the second optical sensor faces the frame.

In this embodiment, the terminal includes two optical sensors. Based on the foregoing description, it can be seen that if the field of view of the first optical sensor faces the display screen and the field of view of the other optical sensor faces the bezel, the distance between the two optical sensors The position between is vertical. 6 is an example diagram of the position of the light source relative to the field of view angle of each optical sensor in an embodiment of the present disclosure. As shown in FIG. 6 , the angle of the light source relative to the first optical sensor below the display screen is θ ₁ The angle of the second optical sensor on top is θ ₂ . It can be seen from the figure that the angle sum of θ ₁ and θ ₂ is approximately 90 degrees. It should be noted that θ ₃ in Fig. 6 represents the angle between the terminal and the ground level.

Based on the above-mentioned Figure 6 and formula (1), if the light intensity detected by the first optical sensor is L1, and the light intensity detected by the second optical sensor is L2, then a system of equations can be established: L1=f(L,θ ₁ ), L2= f(L,θ ₂ ), where θ ₁ +θ ₂ =90°. Since L1 and L2 are known, and the angular relationship between θ ₁ and θ ₂ is known, then L, the actual luminance of the light source, can be obtained.

In one embodiment, the terminal further includes an angle sensor, and the method further includes:

Using the angle sensor, determine a first included angle between the plane where the display screen of the terminal is located and the ground level;

determining a second angle between the light source and the terminal according to the brightness value detected by each of the optical sensors, a predetermined positional relationship between each of the optical sensors, and a preset functional relationship;

A light perception model is established according to the first included angle, the second included angle, and the actual luminance of the light source; wherein the light perception model is used to determine the actual luminance of the light source according to the position of the light source.

In this embodiment, the terminal may also include an angle sensor, such as a gyroscope, which can detect the first angle between the plane where the display screen of the terminal is located and the ground level, that is, θ ₃ in the above-mentioned Figure 6, that is, the terminal the angle of inclination.

In addition, the present disclosure may also determine the second included angle between the light source and the terminal based on the equation set established by the above formula (1). It should be noted that, in the embodiments of the present disclosure, the second included angle between the light source and the terminal may refer to the included angle between the light source and the plane where the warm display screen of the terminal is located, that is, θ ₁ in FIG. 6 .

After determining the first included angle and the second included angle, when combining the actual luminous brightness of the light source to establish the light perception model, in one embodiment, the light source can be determined first according to the sum of the first included angle and the second included angle The first light perception model is established based on the included angle with respect to the ground level and based on the actual luminous brightness of the light source. It should be noted that the first light perception model can be a model obtained by training based on the angles of multiple groups of light sources relative to the ground level and the actual luminance of the light sources, wherein the angles of the light sources relative to the ground level correspond to a light source The actual luminance of luminance is referred to as a group in the embodiments of the present disclosure.

In practical applications, if an angle sensor is installed in the electronic device that provides the light source, the angle between itself and the ground level can be determined based on the angle sensor, and the angle can be sent to the terminal of the present disclosure. The light perception model can directly determine the actual luminous brightness of the light source, so as to adjust the display brightness of the display screen.

Fig. 7 is an example diagram of the included angle between the light source and the ground level in an embodiment of the present disclosure. As shown in Fig. 7 , the included angle between the light source and the ground level is θ ₁ + θ ₃ .

In another embodiment, the second light perception model may be established according to the second included angle, that is, the included angle between the light source and the terminal, and based on the actual luminance of the light source. It should be noted that the second light perception model can be a model obtained by training based on the included angles of multiple groups of light sources relative to the terminal and the actual luminous brightness of the light source, wherein the included angle of the light source relative to the terminal corresponds to the actual luminous brightness of a light source , which is also referred to as a group in the embodiments of the present disclosure.

In practical applications, if the electronic device or terminal that provides the light source is provided with a positioning sensor, the angle between the light source (electronic device that provides the light source) and the terminal can be determined based on the positioning sensor, and the angle is sent to the disclosure The terminal can directly determine the actual luminous brightness of the light source according to the second light perception model, so as to adjust the display brightness of the display screen.

It can be understood that the present disclosure determines the first included angle and the second included angle based on the built-in angle sensor in combination with the above-mentioned scheme including the above formula (1), so as to determine the position of the light source (including the position of the light source relative to the terminal, or the position of the light source relative to The position of the earth level), so as to establish a light perception model to determine the actual luminous brightness of the light source, which can enhance the ability of the terminal in aspects such as automatic dimming.

In one embodiment, the terminal includes a third optical sensor, the third optical sensor is close to the back shell of the terminal, and the field angle of the third optical sensor is toward the back shell of the terminal;

The method also includes:

acquiring ambient light brightness of ambient light other than the light source detected by the third optical sensor;

The determining the actual luminous brightness of the light source according to the brightness value of the light source detected by each of the optical sensors includes:

If the brightness of the ambient light is less than the preset brightness threshold, the actual luminous brightness of the light source is determined according to the brightness values of the light sources detected by the optical sensors.

Since the light intensity of the light source sensed by the optical sensor is more prone to the aforementioned problem of detection deviation in a darker environment, the present disclosure utilizes a third optical sensor whose field of view faces the back shell of the terminal to detect ambient light other than the light source The ambient light brightness, and when the ambient light brightness is less than the preset brightness threshold, determine the actual luminous brightness of the light source, so as to increase the necessity of determining the actual luminous brightness of the light source by using the disclosed solution.

It should be noted that since the light source in the present disclosure includes a point light source or a line light source, the light of a point light source or a line light source cannot pass through an obstruction after being blocked, so the ambient light detected by the third optical sensor in the present disclosure can be understood as Does not include light from light sources.
